One of the most interesting theoretical developments associated with the physics in an isolated, half-filled LL is the proposal in [1]} for the description of the CFL state that is based on an assumption that the
underlying quasiparticles: CFs can be effectively described as Dirac CFs, using
an effective Dirac theory in two dimensions. This can be of general interest: a system of interacting
fermions on a noncommutative (NC) space of an isolated LL, in which they fill half of the allowed, countable states, can be
described by an effective Dirac theory.
